laravel方便调试打印sql日志查看

在实际开发中,我们需要查看拼装的sql是否是自己需要的,为了查看结果,我们直接打印sql.

用DB自带的getQueryLog方法直接打印:

use Illuminate\Support\Facades\DB;
DB::connection()->enableQueryLog(); // 开启QueryLog 2 \App\User::find(1); 3 dump(DB::getQueryLog());

exit;

得到下面的结果,不直观查看:

  array:1 [
    0 => array:3 [
      "query" => "select * from `fook_platform_ordercode` where `fook_platform_ordercode`.`id` = ? limit 1"
      "bindings" => array:1 [
        0 => 1
      ]
      "time" => 11.47
    ]
  ]

我们现在使用另外的一种方式,打印出完整的sql语句,可将以下代码复制到AppServiceProvider中的boot方法中:

代码如下:
\DB::listen(
    function ($sql) {
        foreach ($sql->bindings as $i => $binding) {
            if ($binding instanceof \DateTime) {
                $sql->bindings[$i] = $binding->format('\'Y-m-d H:i:s\'');
            } else {
                if (is_string($binding)) {
                    $sql->bindings[$i] = "'$binding'";
                }
            }
        }

        // Insert bindings into query
        $query = str_replace(array('%', '?'), array('%%', '%s'), $sql->sql);

        $query = vsprintf($query, $sql->bindings);

        // Save the query to file
        $logFile = fopen(
            storage_path('logs' . DIRECTORY_SEPARATOR . date('Y-m-d') . '_query.log'),
            'a+'
        );
        fwrite($logFile, date('Y-m-d H:i:s') . ': ' . $query . PHP_EOL);
        fclose($logFile);
    }
);

那么打印的日志在
